ARRMA MINI KRATON 3S Preload Collar Upgrade MAKM/SC by GPM  [MAKM/SC]

Alloy Preload Collars for 1/16 Mini Kraton 3S

These compact alloy preload collars are an aftermarket tuning item for 1/16 ARRMA MINI KRATON 3S models. Precision-machined from aluminium to ensure consistent seating and to help lower rotating mass on the shock shaft, the collars provide a defined point for spring preload and static ride height adjustment.

Threaded construction with fine-cut threads enables smooth, repeatable changes during races or practice. Anodised surfaces add wear resistance and guard against corrosion from mud and moisture encountered in off-road environments. This item is intended purely for RC suspension tuning and is not a part for real vehicles.

Fitting is simple: slide the collar onto the shock shaft either above the lower spring retainer or under the top retainer, then rotate to achieve the desired preload or ride height. Ensure even installation on each corner and confirm free spring travel after adjustment. Use with correct shaft diameters and compatible springs to preserve expected damping and handling balance.

Set includes 4 pcs aluminium collars suitable for small-scale shock assemblies.
